You didn't answer any my questions . . . on this forum, we use "numbers" not just rhetoric.

I have no idea what you are talking about. What "rhetoric"?
The car has had various combinations of coolant/H2o including straight water at the moment, for testing and constant opening/closing/draining. An engine will run coolest with straight H2o. You know this, right?
My preferred mix is approx. 30% MB factory coolant to 70% distilled H2o normally. I am in SoCal and do not need the freeze protection. In MN., where I am from originally, it is obviously different.
